Ok, image below: -1 to workcrews available to make jobs. And it should be 0, since I just assinged the last free one to the carpentry... Edit: On this same save file it should be visible the rare flying pots of the colony, a really joy for the local tourism. This strange physical phenomen arises from a sudden kitchen demolition, that is so fast and unorganized to take the pots by surprise and leave them stuck in mid air, too confused to fall down due gravity.

Oh, I've got the negative crew count too! Also, the file is Crashy McCrashersons now but was fine for hours - I've turned down the display resolution, updated my drivers, and windowed it and it still just doesn't want to run for more than a day at most. Seemed to run fine until I reached 50+ colonists.
Can you dump the save game for this one, Eva? You sent us the replay - we're looking for the save I think.
